1. A method for providing base service patterns for use in a component-based architecture, comprising the steps of:

  • (a) providing a batch job pattern for structuring batch components such that common architectural services are implemented uniformly across the batch components;

    (b) utilizing a batch unit of work pattern for structuring work to be processed by the batch components so that the work is treated uniformly by the batch components;

    (c) implementing a processing pipeline pattern for structuring batch activities for simplified reconfiguration of the batch activities, wherein implementing the processing pipeline pattern includes preparing to perform a series of processing steps on input objects being streamed into a batch processing system;

    encapsulating each of the processing steps within at least one of a plurality of filters;

    receiving and processing the input objects in at least one of the plurality of filters;

    delivering results from the plurality of filters incrementally during processing of the input objects for reducing latency and enabling parallel processing;

    utilizing connectors for connecting at least two of the plurality of filters each having a processing step for creating a process, wherein one of the two filters is an input filter of the process and the other of the two filters is an output filter of the process; and

    using connectors for connecting input and output filters of different processes for forming a scalable system; and

    (d) using an abstraction factory to encapsulate differences between objects such that only activities that need to understand the difference between the objects have to deal with the differences.
